patented May 2 1933 STATE ta tan FRANKLIN Gr. SLAGEL, 0E BUFFALO, NEW YORK, ASSIGNOB TO FEDDERS MANUFAC- TUBING CUEIPANY, INC 0F BUFFALO, NEW YORK, A CORPORATION OF NEW YORK nvaronaron Application filed December This invention relates to refrigerating apparatus and more particularly to shelf means for evaporators.

An object of the invention is to provide a simple form of shelf means for supporting a pair of pans in the evaporator of a refrigerating system.

Another object of my invention is to provide a shelf means for a pair of superposed trays which is formed of a single sheet of metal and cheaply manufactured.

A further object of my invention is to provide shelf means for insertion in a refrigeration evaporator which is formed of a piece of sheet metal and adapted to support one tray and to suspend another tray.

Other objects of the invention will appear from the following description taken in connection with the drawing, which forms a part of the specification, and in which:

Figure 1 is a perspective view of a refrigeration evaporator and the tray means incor- Figure 2 is a perspective view of the shelf means removed from the evaporator.

Figure 3 is a front fragmentary elevational view of the tray means with pans supported thereby.

Referring now to the drawing by characters ofreference, 10 represents generally an evaporator which is adapted to be connected with a mechanical refrigerating system in the usual manner. The evaporator can take various forms, and as illustrated it is formed of two sheets of metal 11 and 12 which are folded to form a rectangular freezing chamber through an end of which pans 13 can be readily inserted and removed. The outer sheet of the evaporator is formed with a bent out continuous rib 14 which extends from one end to the other of the evaporator to provide a conduit through which refrigerant flows. The sheets are welded together on each side of the rib as indicated at 18, along the ends as indicated at 19, and along the meeting edges as indicated at 15. There is a refrigerant inlet neck 16 at the front end of the evaporator communicating with the conduit and a refrigerant outlet neck 17 extends from the other end of the conduit.

SHELF MEANS 1, 1931. Serial No. 578,365.

Shelf means 20 is provided for supporting two superposed pans within the freezing.

shelf chamber of the evaporator. Such means is preferably made of a sheet of metal which is formed and bent to support one pan thereon and to suspend another pan therefrom. The base portion 21 of the sheet is fiat and formed with a plurality of slots 22 therethrough. The sides 23 of the shelf are parallel and bent downwardly from the base portion and are formed with an inwardly extending bead 24 forming a guideway. The ends of the sides are turned inwardly and folded upon themselves to form supporting flanges 25 for one of the pans, while the ends 26 of the base are folded under to reinforce the structure and to provide a grip by means of which the shelf can be grasped while inserting or removing from the evaporator.

The evaporator is formed on its inner side walls with parallel guides 27 which interfit with the beads 24 of the shelf means and serve as a supporting and guide means therefor. The ends of the sheet of metal are cut out suficiently on each side so that the base ends can be folded without interference The shelf means is preferably removable from the evaporator, but if desired it can be permanently secured therein. A pen can be supported upon the base of the shelf means, and another pan can straddle and be suspended from the fianges25 of the shelf means. The suspended pan is formed with extended side portions 28 which overlap and rest on the supporting flanges 25 in a relation such that the pan can be moved endwise for removal or insertion. The shelf means is supported in the evaporator so that either pan, carried thereby, can be readily inserted or removed from the evaporator.

The shelf means, herein described, for supporting a plurality of pans can be cheaply manufactured and readily associated with or removed from operative relation with an evaporator.

Although this invention has been described in connection with a specific embodiment the principles involved are susceptible o numerous other applications which will readily occur to persons skilled in the art,

and the invention is therefore to be limited only as indicated by the scope of the ap pended claims.

What I claim is: v

1. A shelf means for su porting pans in superposed relation in a re rigeration evaporator, comprising a base, sldes extending downwardly from the base each formed with an inwardly extending guideway, and inturned flange at the bottom of the sides.

2. A shelf means for supporting pans in superposed relation in a refrigeration evaporator, comprising a sheet of metal formed with a perforated base, downturned sides having pressed in guideways, folded under base ends, and folded flanges extending inwardly from the bottom of the sides.

3. The combination with an evaporator having a chamber formed with oppositely positioned guides, of a shelf means for supporting pans in superimposed relation in said chamber, comprising a base portion adapted to support one pan, sides extending from said base portion and formed with inwardly extending flanges adapted to support a second pan, said sides being formed with mounting portions adapted for interconnection with the guides in said chamber.

In testimony whereof I afix my signature.
